"She's just had the best attitude of fight and then move forward with life," Devon, 26, tells PEOPLE of his daughter. "And look where we are now. I'm getting married to my love and Leah gets to be a part of this wedding. We overcame tragedy and are becoming a family. It's like a fairy tale."

Nearly two years ago, the recently signed Houston Texans defensive tackle and his fiancé Asha Joyce put their wedding plans on hold after Leah was diagnosed with the deadly disease. Doctors gave her a 50-50 chance of survival.

Devon publically documented his daughter's two-year battle on social media, and officially announced that she "beat cancer," in January.
